Dennerle Aquarium Starter Rapid is a highly effective product for a rapid, safe start for newly established aquaria. It is made up of two components:

1. Living filter bacteria – they settle on filter material and gravel and instantly begin breaking down pollutants. The bacteria solution is highly concentrated, with a guaranteed 500 million bacteria per millilitre (when filled).
2. Bacteria booster nutrient solution - the specially developed "bacteria food" ensures rapid growth and reproduction.

How it works:

  • Powerful nitrification bacteria (Nitrosomonas, Nitrobacter) convert harmful ammonia into nitrate via nitrite, detoxifying the water
  • In the anaerobic areas of the aquarium - primarily in the substrate and the filter - denitrifying bacteria (Paracoccus) convert nitrate into gaseous nitrogen, reducing the nitrate content.
  • The filter bacteria also break down dead plant matter and food residues, fish excrement, organic impurities, proteins, fats, carbohydrates, harmful organic substances and organic sludge
